The answer is D because it makes more sense than all of the other ones
Answer:
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
is the constant of a certain reaction at equilibrium for gaseous reactants and products.
For the given chemical reaction:
The expression of for above equation follows:
As solids do not exert pressure, and are not involved.
Answer: T<span>
etrafluoroethene (F</span>
₂CCF₂<span>
) undergoes polymerization describes the formation of Teflon.
Explanation: Polymerization is the process in which small units called as
monomers join together repeatedly and forms a long chain macro-molecule called as
polymer.
In given question the monomer is Tetrafluoroethene because alkenes can undergo polymerization via Addition polymerization via following mechanism.
a) Free Radical Addition Reaction
b) Acid Catalyzed Addition Reaction
c) Base catalyzed Addition Reaction
The formation of
Teflon from Tetrafluoroethene is shown below,</span>
Techneutim(Tc) has 43 protons, 43 electrons and 54 neutrons.
C = 0.11 mol
V = 5.65 L
n = ???
n = C*V
n = 0.11 * 5.65
n = 0.622 mols
1 mol of CaCl2 = 40 + 2*35.5 = 111 grams
0.622 mol = x
x = 111 * 0.622
x = 69.0 grams CaCl2
